My 2c (USD) is for clarity on ADT vs. SDK vs. Toolchain.
The biggest clarify problem I've seen is the terms being intermingled. There
are clear definitions for each.
Toolchain, the compiler and related tools that enable compiling software for a
given target.
SDK - Software Development Kit - On OE-Core this purpose of this is to enable
developing software to be run on a specific target environment, generally also
constructed from OE-Core. The SDK consists of three primary components:
1) environment setup files - these configure the compilation environment with
the right settings
2) nativesdk software - these are applications that run on the -host- system
to assist in compiling software for the target (this includes the target toolchain.)
3) target sysroot - The sysroot is the collection of libraries, headers and
assorted items that are compiled for the target. A sysroot is setup in a
similar fashion as a target's root filesystem.
ADT - Application Developer Tool - This is an Eclipse component that can use the
SDK, generated by OE-Core, to enable application development within the Eclipse
framework. (I may be slightly wrong on this item, as people have told me in the
past there are command line parts to the ADT.... but the ADT itself is -not- the
SDK.)

Subject: [yocto] IMHO, cross-compile/toolchain examples should use non-
x86 arches
a general preference on my part, but i think it would be useful if any
yocto
docs that are discussing toolchains or cross-compilation or the like use
*non*-x86 architectures to get the point across.
for example, consider the current application developer's guide.
part of it uses, as an example, the toolchain installer
poky-eglibc-x86_64-i586-
toolchain-gmae-1.4.sh. while this works just fine, of course, what it
does is
potentially co-mingle both the dev host content and target host content,
making it harder than necessary for the reader to draw a clear distinction
between the two.
if any example related to compilation or a toolchain involves, say, an
*arm*
target, then it's *immediately* obvious (using the "file"
command) whether something belongs on the dev host or on the target.
also, if you're using x86 for both dev content and target content, you
run
the risk of an example working by accident since you're picking up
natively-
installed tools when you shouldn't be. if you use a non-x86 arch, there's
little
chance of that happening.
just my $0.02 (Cdn).
